ERNST GLANTZBERG, OF SPRINGFIELD, MASSACHUSETTS.

SPECIFICATION forming part of Letters Patent No. 765,423, dated July 19,1904.

Application filed April l, 1903. Serial No. 150,597. (No model.)

To all whom, t may concern:

Be it known that I, ERNST GLANTZBERG, a citizen of the United States ofAmerica, and a resident of Springfield, in the county of Hampden andState of Massachusetts, have invented certain new and usefulImprovements in Heating and Ventilating Apparatus, of which thefollowing is a full, clear, and exact description. l

This invention relates to improved apparatus for heating andVentilating, having for its object to acquire especially a better andmore equable maintenance of a desired temperature within an apartment orseries of apartments, the air to be introduced into the apartmentsubject to controlled heating arrangements therefor being always freshand pure as taken either from the exterior of the building or otherwise.

A prominent characteristic of this invention is found in the arrangementwithin an air-supplying flue leading to a room of separate steamheatedradiators having at and for the respective steam-inlet supply-pipestherefor val ves, preferably of the kind known as diaphragm-operatedValves, together with separate thermostats, one located Within theapartment and subject to the temperature changes therewithin and theother located outside of the building and subject to the temperature orweather changes, each said thermostat being operatively connected withthe controllers of the respective valves, whereby the radiators willheat the air in transit through the air-Hue leading to the apartment, asthe heating thereof may be controlled or regulated by the temperaturecondition both within the room and out of doors.

Features of invention furthermore reside in combinations andarrangements with the flue having the thermostatically-controlledair-heating apparatus therein of air-blowing and air-damping devices, ashereinafter set forth.

An illustration of my improved heating and Ventilating apparatus isprovided in the accompanying drawing, in which the same is shown inconjunction with a sectional elevation of a portion of a building havingan airsupplying flue leading from a lower portion into a room therein.

In the drawing, A represents a portion of a building having in the wallthereof an airline B, which leads from its air-receiving location in thebasement, through a portion of the building, to a room thereabove.

Located in the lower portion of the air-flue B are radiators I and E,for whichz' and e are the steam inlet and supply pipes, having,respectively, the valves 2 and e2 for closing and opening, more orless,.the steam passage-way through each of said steam-pipes, thesevalves vbeing advantageously automatic controllervalves of thediaphragmtype.

R represents the thermostat, located in the apartment C and havingoperating connection i with the diaphragm-valve 2, and W indicatesanother thermostat at the exterior of the building, having operatingconnection e* with the diaphragm-valve e2. Manifestly excessive heat inthe room C will result in such an operation ofthe valve 2 as to decreasethe heating action of the radiator I, lowering of the temperature in theroom being operative to increase the heating effect of such radiator I,and the radiator E is independently controlled bythe Weather-thermostat,so that in extremely cold Weather the radiator E Will receive a maximumsteam-supply therein, while in mild Weather such radiator will receivelittle or no steam therein.

The radiators are preferably located in or near the base of the flue B,which supplies air to one or to a series of rooms and connected with theHue below the radiators as an airconduit J, having a fan or blower gtherein and having a damper /L for opening and closing the conduit J.

K represents an entrance-opening for air leading from the exterior ofthe building through the Wall at the lower portion thereof, also to thebase of the iiue belowthe radiators, and this opening has adamper c, thedampers t and c being supported on journal-rods h2 and k2, each of whichhas a lever-arm if and 7c3, which are connected by the link or rod Z,the latter and the levers being so relatively arranged to thedamper-rods that when one damper isA open the other will be closed, and,

-or both dampers may be partially open, so

that it is possible to establish an air-supply as blown into the base ofthe Hue from within the basement or as drawn into the base of the Huefrom 'out of doors to be subjected to the heating' action ot' bothradiators as controlled by the temperature conditions both within andoutside of the apartment to be heated and ventilated, and ofcourse asomewhat restricted quantity of air may be supplied at the base of theHue under the radiators from both within the basement and the exteriorof the building.

Iclaiml. In an indirect air-heating apparatus, a building having anair-supply Hue leading to an apartment therein, separate heating deviceslocated in said Hue, separate controlling means for each heating device,and a separate thermostat for each controller, one located within thesaid apartment and subject to the temperature changes therewithin, andthe other located outside the building' and subject to the weathertemperature, each thermostat being 'operatively connected with thecontrolling means of its respective heating device, the a1'- rangementbeing such that each heating device is thermostatically controlled, onefrom within the building and the other from with- Out.

2. In an indirect air-heating apparatus, a building having a Hueleading' from the outer atmosphere into an apartment Within thebuilding, separate steam-heating' radiators located in the lower portionof said Hue, independent steam-inlet supply-pipes for said radiators, acontroller-valve for each steam-supply pipe, a separate thermostat foreach controller-valve, the thermostat for the controllervalve of oneradiator being located within the apartment and subject to thetemperature changes therein, and the thermostat for the controller-valveof the other radiator being located outside of the building and subjectto the weather temperature, and each thermostat having' an independentoperative connection with its controller-valve, the arrangement beingsuch that each radiator is thermostatically controlled, one from withinand the other from without the building'.

3. In an indirect air-heating apparatus, a building having an air-supplyHue leading from the basement thereorl to an apartment above thebasement, said Hue communicating at its base by separate openings withthe outer atmosphere and with an apartment in the basement of thebuilding, separate valves for reversely controlling said Hue-openings,and means common to both of said valves for simultaneously opening' oneand closing the other, and vice versa, separate steam-heating radiatorslocated in the lower portion of said Hue, independent'steam-supply pipesfor said radiators, a controller-valve for each steamsupply pipe, aseparate -thermostat for each controller-valve, the thermostat for thecontroller-valve of one radiator being located in the apartment andsubject to the temperature changes therein, and the thermostat for thecontroller-valve oi' the other radiator, being located outside of thebuilding' and subject to the weather temperature, and each thermostathaving' an independent operative connection with its controller-valve,the arrangement being such that each radiator is thermostaticallycontrolled, one from within and the other from without the building'.
